IMAGE TREMOR CORRECTION DEVICE AND CONTROL METHOD OF THE SAME, OPTICAL DEVICE, AND IMAGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image tremor correction device that attains an excellent image tremor correction even when a large tremor occurs upon a panning operation and the like.SOLUTION: An imaging device is configured to perform a feedback control so that a location of a tremor correction lens converges to a target location, and an LPF 508 and a subtraction part 515 are configured to divide a tremor signal into a low frequency component and high frequency component. An addition part 520 is configured to synthesize each output of a high frequency LPF 507 and low frequency LPF 511, and output the target location of a tremor correction lens. A pan/tilt determination unit 504 is configured to determine a panning velocity from the tremor signal. Upon quick panning, a control is configured to be performed to cause the target location of the low frequency and high frequency to converge to a zero, and upon an end determination, a target location computation of the high frequency is configured to start earlier than that of the low frequency. Upon slow panning, the control is configured to be performed to cause only the target location of the low frequency to converge to the zero. The pan/tilt determination unit 504 is configured to change a determination condition for detecting the slow panning at a time of a hand-held shooting and in a static state where a camera is mounted to a tripod.
